So it seems that your problem is not POD-related, but is tied to your Python interpreter which is not fully UNO-compliant.
OpenOffice ships with a UNO-compliant Python interpreter, is it the one you use? Typically such an interpreter can be found in <where_you_installed_OO>/program
In the Renderer you can specify a param with the path to a UNO-compliant Python interpreter, if the one running appy.pod isn't.
